ROBERT L. HORSLEY, OF FORT WORTH, TEXAS.

WIRE STRAIGHTENING AND COILING MACHINE.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed March 27, 1907. Serial No. 364,799.

To all whom it may concern:

Be it known that I, ROBERT L. HoRsLEY, a citizen of the United States, residing at Fort Worth, Texas, have invented a new and Improved Wire Straightening and Coiling Machine, of which the following is a specification.

This invention relates to a machine for forming wire into spiral form without twisting the wire and to wire straightening mechanism, and the object is to provide a machine which will form spirals of any desired diameter and ofany desired flight and which is provided with suitable adjusting means for forming different sizes of spirals.

Another object is to provide such machine with means for cutting all spirals of a uniform length as soon as formed.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and specification.

Figure 1 is a plan view of the machine. Fig. 2 is a side elevation of the same. Fig. 3 is an end elevation of the same. Fig. 4 is a detail view of the bending pulley and the carrier for said pulley. Fig. 5 may be called a plan view of the former and Fig. 6 an edge View of the same. Fig. 7 is a front view of the cutter. Fig. 8 is an edge view of the same. Fig. 9 is a side view of the feeding pulleys. Fig. 10 is an enlarged view of the cam link. Figs. 11 and 12 illustrate the flight regulating bars. Fig. 13 is a plan view, illustrating a variation in the former. Fig. 14 is an enlarged view of one of the yokes shown in Fig. 13. Fig. 15 is an edge view of the central block or former shown in Fig. 13.

Similar characters of reference are used to indicate the same parts throughout the several views.

This machine is provided with a platform 1 which is supported by upright legs 2 and 3. The spiral former 4 is mounted on the end of a hollow rotary shaft 5. The shaft 5 is journaled in bearings 6 which are attached to platform 1. A pulley 7 is mounted on the hollow shaft or guide 5. A belt 8 is placed on the pulley 7 and is, driven from the shaft 9 making a quarter turn. The shaft 5 serves as a shaft for rotating the former and also as a guide for directing the spiral to the cutter.

The former 4 has a rectangular block 10 which has a lateral opening therethrough for the blocks 11 and 12. The blocks 11 and 12 regulate the flight of the spiral of the wire. The flight regulating blocks 11 and 12 are adjustable and are held in-diflerent adjustments by set bolts 13. The bearing portion of block 11 is cylindrical and the bearing portion of the rear or receiving block 12 is also cylindrical. This block 12 may be provided with annular grooves 14. These grooves are for receiving the wire as it is fed to the machine. When the wire wears the block to a considerable extent, the block may be shifted lengthwise so that the wire will be received in the neXt groove 14. After the wire passes the block 12 and before it passes to block 11 it runs over a grooved pulley 15 which bends the wire between blocks 1 1 and 12. The pulley 15 is provided with a carrier 16 which runs through the block at right angle to the blocks 11 and 12. The carrier 16 is screwthreaded at the outer end and is made adj ustable in the block 10 by a nut 17 by which the pulley 15 can be made to bend the wire .more or less and thus increase or decrease the diameter of the spiral of the wire. If the carrier 16 is screwed downwards far enough to bring the surface or periphery of the roller 15 below the upper surfaces of the blocks 11 and 12 the wire would not be bent at all. If the carrier 16 is screwed upwards so that the surface of the roller 15 is above the surfaces of the bars 11 and 12, the wire will be bent as the former block 10 is revolved about the wire and the more the carrier 16 is screwed upwards the greater will be the diameter of the spiral when formed. The flight of the spiral may be increased by moving the blocks 11 and 12 further apart and the flight may be decreased by moving the blocks 11 and 12 towards each other. The blocks 11 and 12 may be held at any adjustment in the longitudinal slot in the block by the set bolts 13. After'the wire is formed into a spiral it is guided to the cutter located on the front of the machine. The shaft 5 guides the spiral to the cutter.

The wire is to be cut of a uniform length which is the main driving shaft, the belt 8 I during the continuous operation of the madownwards.

grooved pulleys 34 and 35.

chine, but the cutting mechanism can be set to cut the wire of any desired lengths. A standard 18 is attached to the end of the machine. A stationary cutter 19 is located near the top of the standard 18. clamped to the standard 18 by means of a screw bolt 20. The screw bolt 20 may be loosened and the cutter 19 raised or lowered by the 'screw 21 for the purpose of adjusting the same. A movable blade 22 is mounted on the lower part of the standard 18 by means of bolts 23 and the blade has slots 24 so that the blade can move upwards and The blades 19 and 22 are in alinement with the guide-shaft 5 so that the spiral wire is fed between the blades. The blade 22 is actuated by a cam 25 which forms a link in the sprocket chain 26. This chain may be lengthened or shortened so that the cam 25 will actuate the cutter to cut the wire at the proper length. A spring 42 may be attached to the standard 18 and to the blade 22 so that the blade will be brought promptly back to its normal position. The sprocket chain 26 is mounted on a sprocket wheel 27 which is driven by the shaft 28 and on an idle sprocket wheel 29. The shaft 28 is journaled in bearings 30 and 31 which are attached to the upright legs 3. A balance wheel 32 is mounted on shaft 28. The shaft 28 is driven by a sprocket chain 33 which is driven from the main driving shaft 9. The idle sprocket wheel 29 may be located at any suitable place relative to the shaft 28, as shown in Fig. 8 or as in Fig. 2. When the chain 26 is driven the cam 25 will move the blade 22 up to cut the wire which is passing between the blades 22 and 19. As soon as the cam 25 passes the lower end. of the blade 22, this blade will assume its normal position.

Means are provided for driving wire through the former 4. This is done by two The pulley 34 is mounted on a shaft 36 which is driven by a sprocket wheel 37. Sprocket wheel 37 is driven by the sprocket chain 38 which is driven by the sprocket wheel 39 which is driven by the main driving shaft 9. A pinion 40 is mounted on shaft 36 and drives apinion 41. Pinion 41 is mounted on and drives the shaft 42 which carries the pulley 35. The shaft 36 has a slight vertical movement in its bearings so that the pulley 34 will yield to prevent binding of the wire between pulley 34 and pulley 35. The bearing of pulley 34 is pressed downwards by a bar 43 which is pressed down by the spiral springs 44 and these springs 44 are pressed downwards by the bar 45. A guide is necessary for directing the wire to the pulleys 34 and 35. A support 46 is attached to the platform 1 and a guide 47 is mounted in the support 46. The wire feeds through the guide 47 to the pulleys 34 and 35. The machine can also be used for straightening wire as well as for coiling The cutter 19 is wire. For straightening the wire it is only necessary to adjust the pulley 15 and the blocks 11 and 12.

Figs. 13, 14, and 15 illustrate a variation in the former. The block 50 is similar to block 10 except that the slot, corresponding to the slot for the movement of blocks 11 and 12, extends to the end of the block. Bending blocks 51 and 52 are mounted in block 50. Block 51 is made adjustable laterally by nuts 53. The advantage of the lateral adjustment is that when the block wears it may be shifted laterally so that the wire will engage the block at a different place. Yokes 54 engage the block 51 and clamp the block 52 to hold the same in place. The block 52 can be placed at different adjustments relative to the block 50 and the yokes 54 and clamped at the different adjustments by bolts 55 which are screwed into the lower jaw of the yoke. Set bolts 56 are also used to clamp the blocks 51 and 52 in the block 50.
